PAM_NOLOGIN(8) NetBSD System Manager's Manual PAM_NOLOGIN(8)
NAMEpam_nologin -- NoLogin PAM module
SYNOPSIS
[service-name] module-type control-flag pam_nologin [options]
DESCRIPTION
The NoLogin authentication service module for PAM provides functionality
for only one PAM category: authentication. In terms of the module-type
parameter, this is the ``auth'' feature. It also provides a null func-
tion for session management.
NoLogin Authentication Module
The NoLogin authentication component (pam_sm_authenticate()), always
returns success for the superuser, and returns success for all other
users if the file /etc/nologin does not exist. If /etc/nologin does
exist, then its contents are echoed to non-superusers before failure is
returned. If a "nologin" capability is specified in login.conf(5), then
the file thus specified is used instead. This usually defaults to
/etc/nologin.
The following options may be passed to the authentication module:
debugsyslog(3) debugging information at LOG_DEBUG level.
no_warn suppress warning messages to the user. These messages include
reasons why the user's authentication attempt was declined.
